Solaris zones - checking processes and lofs file system
Hi all,

q1) If i am in a global-zone, is there any command or anyway to check if a particular process in "ps -ef" output is running in which zone ?

q2) if i have created and mount a lofs filesystem/mountpoint for my non-global zone, can i say the following

e.g.
/dev/md/dsk/d60 /data -- globalzone
mkdir -p /data/myzone/newinfo
mount -F lofs /data/myzone/newinfo /zones/myzone/root/data/newinfo

- there is a possibility that users might delete files in the localzone FROM the globalzone
- there is no way in for a localzone to view/delete files from lofs filesystem that belong to the globalzone

right ?

q3) is there anway i can isolate device/harddisk to localzone, so that users in globalzone, is not able to go directly into the filesystem/path to delete folders.
-- to export entire fs to a localzone (add fs set special/set raw etc..)
-- to export endire disk to a localzone (add device / set match)

right ?

Regards,
Noob

LEARN ABOUT OPENSOLARIS

dev

dev(7FS)							   File Systems 							  dev(7FS)

NAME

       dev - Device name file system

DESCRIPTION

       The  dev  filesystem  manages  the  name  spaces  of devices under the Solaris operating environment. The global zone's instance of the dev
       filesystem is mounted during boot on /dev.

       A subdirectory under /dev may have unique operational semantics. Most of the common device names under /dev are	created  automatically	by
       devfsadm(1M).   Others,	such  as  /dev/pts,  are dynamic and reflect the operational state of the system. You can manually generate device
       names for newly attached hardware by invoking devfsadm(1M) or implicitly, by indirectly causing	a  lookup  or  readdir	operation  in  the
       filesystem to occur.  For example, you can discover a disk that was attached when the system was powered down (and generate a name for that
       device) by invoking format(1M)).

FILES

       /dev    Mount point for the /dev filesystem in the global zone.

SEE ALSO

       devfsadm(1M), format(1M), devfs(7FS)

NOTES

       The global /dev instance cannot be unmounted.
